Method Detail

registerObservers

public void registerObservers(ObservableWrapper o)

Overrides:

registerObservers in class Modeler

addParams

public void addParams(javax.swing.JPanel controlpanel)

getModelType

public int getModelType()

Description copied from class: Modeler

returns one if model is of distribution and needs to be rescaled for display. Returns 0 if model does not require scaling. EG: Polynomial fit is type 0 and normal distribution is type 1.

Overrides:

getModelType in class Modeler

getLowerLimit

public double getLowerLimit()

Description copied from class: Modeler

return the allowable x limit values. This method should return the lower limit. eg: for a normal distribution lowerlimit = NEGATIVE_INFINITY

Overrides:

getLowerLimit in class Modeler

getUpperLimit

public double getUpperLimit()

Description copied from class: Modeler

return the allowaable x limit values. This method should return the upper limit. eg: for a normal distribution upperlimit = POSITIVE_INFINITY

Overrides:

getUpperLimit in class Modeler

returnModelX

public double[] returnModelX()

Description copied from class: Modeler

returns the fitted model values for X axis

Overrides:

returnModelX in class Modeler

returnModelY

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent event)

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

generateSamples

Description copied from class: Modeler

generates samples from the distribution and returns a double[] data type

Overrides:

Description copied from class: Modeler

return the number of models to be plotted. If n models are returned, the vectors from returnModelX and returnModelY will be split into n equal sub sections and plotted

Overrides:

getModelCount in class Modeler

Returns:
